(SIGNAL-LANTERN.

SPECIFICATION forming part of Letters Patent No. 393,460, dated November 27,1888.

Application filed Se; tcmber 10, 1887. Serial No.:-19,288.

To all whom it may concern:

Be it known that we, ANDREW J. GooLaY and JOHN S. KENDIG, of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvenlents in Signal-Lanterns; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of our invention is to enable a signal-lantern burning coal-oil to be used in blasts of wind without affecting the light. To attain this end, we have devised the construction and combination of parts hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 represents a vertical section of the lantern cut through the cap and support. Fig. 2 represents a similar view taken at right angles to Fig. 1 through the center of the glass disk. Fig. 3 represents a horizontal section of the same, taken above the lamp. Fig. 4 represents a plan view of the lantern with the cover thrown back. Fig. 5 represents, on a smaller scale, an elevation of the lantern, taken from one of the sides having the glass disk.

A designates the rectangular casing of the lantern, having a bottom, A, in which are holes a near two of its sides. On two opposite sides the lantern is provided with glass windows 13, preferably circular, which are set into metallic annular sockets 0, formed with casing A. These sockets are provided with flanges c at their inner edges for preventing the glass from entering the lantern. To secure the glass externally,a ring,D, isinserted within said socket, bearing against the outer face of the peripheral part of the glass. The outer edge of each ring D is bent over the project ing outer edge of said socket, rendering these parts of the lantern air-tight. One of the other sides of the casin g A is provided with a socket, E, for receiving the upper end of a pole or similar support. The fourth side of said casing A is provided with a hand-hole for insert ing,withdrawing, and extinguishing the lamp. This is surrounded by an outwardly-extending collar, F, formed with said casing. A cap,

G, fits within said collar, its inner edge coming against a small internal annular flange, f,

(No model.)

is provided at its outer corner with a similar external flange, g, which fits against the outer edge of the collar, these flanges making the joints air-tight. The cap G is provided with a handle, G.

The perforations a in the bottom A, already referred to,are along the two sides of the lantern. They admit air into horizontal airducts H, which connect with vertical flues I, each consisting of several overlapping funnelshaped tubes, i, extending upward along the inner face of the casing A on opposite sides thereof. The uppermost tube ion each side is inclined toward the other flue I in a position more nearly horizontal than vertical. \Vhere the upper tubes, '11, of each side approach each other, a shield, J, is placed below and in front of their ends.

The middle of the top of easing A is pro vided with an upwardly-extending truncated cone, K, open at the top. The upper edge of this truncated cone is provided with an annular flange, 7:, extending outward and downward as a wind-guard. Standards S, rising from the upper edge of said truncated cone, support a horizontal heat-guard, L, above the opening in the top thereof. A cover, M, having the shape of a cylindrical box open at the bottom only, is hinged at m to the top of casing A,and secured thereto at an opposite point by a spring-catch, N, which allows said cover to be turned back at will. This cover has perforations m in it near its base,which supply air below the wind-guard, before mentioned. \Vhen secured by the spring-catch N, it incloses and protects the aforesaid cone, windguard, and heat-guard. It is provided with a bail, 0, whereby the lantern is carried. Putty is used for more effectually scaling the glass windows. The lamp P rests on the bottom A within a socket, p.

The air enters only through the perforations a in the bottom A, whence it passes along through air-ducts H and upward through fines I over the top ofthe fender J to the space above the lamp 1?, then up through the truncated cone K, and finally out through perforations m. The wind-guard It prevents a sudden blast of air from rushing in through these lastnamed perforations and descending on the lamp. The heat-guard L prevents theheat of at the base of said collar, while the cap itselfl the lamp from injuring the cover M. The

ICO

flame is effectually protected,by the construction above described, against sudden blasts of air, but may easily be extinguished at will by withdrawing the cap G and allowing air to rush in.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1.'Iu combination with alautern casinghaving an npwardly-extending cone, K, open at the top, and a deflector, 7c, flaring outwardly and downwardly from the edge of this opeuing. a cover, M, attached to said casing and in closing said cone and deflector, said cover being provided with holes at in its side below the level of said deflector,and the latter being imperforate and connected at its base to the top of the lantern-easing, in order that there may be no communication between the interior of said casing and the holes m, except through the top of said cone and above said deflector, substantially as set forth.

2. In combination with a lantern casing having openings for air in its bottom, aseries ANDREW J. COGLEY. JOHN S. KENDIG.
